What is Project Explorer 'Harvesting'?

ive come across Project Explorer recently and not having used it previously, it seems quite useful. Upon testing it, when i click 'Models' PE then harvests a lot of files. Ive not been able to get to the end of its harvest to see what its harvesting. Any ideas as it seems to be harvesting more than what is directly referenced, which is what i assumed is the harvest?

Harvesting is based on configuration variables, for instance you could harvest all Sheet models from the active directory (_DGNdir). This would then list all the sheet models in the directory of the active file. In your case (based on the description) it is going to return a list of all the models. I don't have enough information to say where it is harvesting the list of models from.
